It's hard to believe, but UFC superstar Ronda Rousey still has her doubters. Fresh off her 14-second dismantling of Cat Zingano, Rousey was doing an interview with a man named Aaron Tru, who told her, "I don't think you have as much strength and can compete with a man."

Well, that was a dumb thing to say. Not since Bobby Riggs squared off with Billie Jean King has the gauntlet been thrown down so hard in the battle of the sexes.

At first Rousey tried to laugh off Tru's comment, then proceeded to throw him down, leaving him in total agony and fearing he broke a rib or two. (As it turns, out he broke four.) Rousey expresses some concern, but she needn't have worried. Tru pretty much painted himself into a corner and can only wish he'd make it 14 seconds in a fight with her.
